XR33053
Low Power Shutdown Mode
Low power shutdown mode is initiated by bringing both RE
high and DE low simultaneously. While in shutdown devices
draw less than 1μA of supply current. DE and RE may be
tied together and driven by a single control signal. Devices
are guaranteed not to enter shutdown if RE is high and DE
is low for less than 50ns. If the inputs are in this state for at
least 600ns, the parts will enter shutdown.
Enable times t_ZH and t_ZL apply when the part is not in low
power shutdown state. Enable times t_ZH(SHDN) and t_ZL(SHDN)
apply when the parts are shutdown. The driver and receiver
take longer to become enabled from low power shutdown
t_ZH(SHDN) and t_ZL(SHDN) than from driver or receiver disable
mode (t_ZH and t_ZL).
